The system is self-contained, giving the astronaut flexibility and control in a weightless environment, and allows for a simple and hygienic disposal. The paper on the round end was removed to expose an adhesive portion that astronauts could affix to themselves and use to seal the bag after use. A germicidal tablet was then activated inside the bag to kill bacteria and the bag was placed in a containment bag for storage and disposal.
